Abstract

A perfusion system comprising an implantable access device with two separate chambers (10, 12) accessed via a septum (16, 18), said chambers being arranged one above the other so that when the infusion or sampling needle is inserted into the lower chamber (10) by passing it through the respective septum (16), said needle also passes through the septum (18) of the upper chamber (12). The system further comprises an infusion device consisting of two rigidly connected parallel needles (36, 38) having different lengths, such that when the longer needle (38) is inserted into the lower chamber, the shorter needle (36) is also inserted into the other chamber. The infusion device with two rigidly connected needles avoids any danger of tearing which may lead to extravasation.
